Pergamon

Pergamon, also known as Pergamum, was a Greek city-state in Asia Minor, isolated from the other of The Greek Cities by the Mediterranean Sea. Pergamon was a target of the Antigonid Empire, so they allied with Rhodos against the Macedonians and beat them in the Battle of Chios in 201 BC. Pergamon was eventually conquered in 129 BC by the Roman Republic, Pontus, and Cappadocia.
